NIAGARA FALLS, N.Y. (WKBW) - Two people are in federal custody after five Rochester children missing since August were found at a home in Niagara Falls Wednesday.

Mark Johnson and Ise-Lynn Johnson were arrested by U.S. Marshals. According to investigators, both suspects are related to the children.

"I'd say hello but they never spoke," said Deborah Jones who lived across the street from the Johnson's. "So I thought I hope it's good neighbors moving in across the street, but they stayed to themselves. So I thought that was good... not knowing they were hiding children."

The five children, ages 12, 11, 10, 8 and 5, were reported missing by a family member in Rochester last summer.

"They were younger kids," said other neighbor Steven Seekens. "It was just really weird to see them. I had never really seen them before but I thought they were random kids just running around."

"I never saw any kids... that's stunning," said Jones. "To know you've got kids cooped up in the house like that! I'm shocked knowing that... you don't know your neighbors!"

After extensive investigations in the Rochester and Buffalo areas, the U.S. Marshals Task Force found out Mark and Ise-Lynn Johnson were staying at a home in Niagara Falls with the children.

U.S. Marshals executed a search warrant at the home, where they found all five children, along with the alleged abductors.

"I saw the Marshals in the grey undercover car get back in the car with his gun and I was wondering why he was there," said Jones.

Both were wanted by the Rochester Police Department for endangering the welfare of a child.
